CAMAC - 3640 4-channel, Up-Down Presettable Counter View Datasheet Request Ordering Information     ABOUT 3640 The Model 3640 is a single-width CAMAC module containing four presettable, 16-bit, up-down counters. These counters accept TTL signals at rates from dc to 20 megahertz from either the front-panel LEMO connectors or the printed circuit edge connector. Each counter can be read as well as written. Counting can be inhibited by Dataway Inhibit or from an external inhibit signal; a front-panel switch enables the Dataway Inhibit. Counters can be individually cleared by Dataway command, and they can be connected in series for increased count capacity. Each counter has both an overflow and an underflow LAM status bit. The resulting eight LAM status bits can be read and cleared individually or inpairs as the associated counter is cleared.
